BACKGROUND: Superior mesenteric artery aneurysm (SMAA) represents a rare but potentially fatal condition. This study aimed to present the individual management protocol of SMAA in our center and to discuss a potential preliminary treatment algorithm.
METHODS: SMAA patients treated in our center between January 2007 and December 2014 were retrospectively reviewed on January 2015.
RESULTS: Sixteen patients with SMAA were identified, including 1 female and 15 males, with a mean age of 48.9 ± 12.9 years. Three patients (3/16, 18.8%) were treated by multiple overlapping bare stents and one (1/16, 6.3%) initially by a single bare stent. Two cases (2/16, 12.5%) were treated by a covered stent implantation, but one of those suffered from SMAA rupture 7 days later, whereas the other had inner-stent thrombosis one month after discharge and died from multiple organ-dysfunction syndrome. Nine patients (9/16, 56.2%) received conservative therapy, one of who received multiple overlapping bare stents implantations for persistent abdominal pain. One patient underwent open surgery. There were 2 major complications, with no death during hospitalization and 1 death during follow-up.
CONCLUSIONS: SMAA treatment needs to be individually prescribed, based on clinical manifestation, anatomy, and etiology. Multiple overlapping bare stents are safe and effective in selective patients with SMAA, and covered stents should be used with caution to avoid covering proximal branches; open surgery should be reserved for patients with suspected intestinal necrosis.
